Unarmed Pillagers Still Shoot

I was playing on my world in Minecraft today and I wanted to create a pillager jail in a village. So I created a jail, spawned some pillagers in and used a command to remove the pillager's crossbows. Soon, I went into Survival to test the prison if it is escape-proof. I started at a jail cell to see if there was a way pillagers could escape. Then, I was attacked. I was trying to find out what was attacking me, so I gave myself Resistance 100. When I went into the jail cell, pillagers were firing at me even without their crossbows. I was kind of confused because I thought they couldn't shoot without their crossbows.
